Oct 11, 2018 at 8:35 | comment | added | Memphisd | @lcv Unfortunately, Markov gives a bound on not getting to many collisions, but lower bounding the probability of obtaining at least $L$ collisions seems not possible. Markov $\Pr[X\geq \alpha\cdot\mathbb{E}[X]]\leq\frac{1}{\alpha}$. For $\alpha\leq1$ the bound collapses to something trivial. Which is quite intutive, cause theoretically, it could be possible, that in most iterations far less than $L$ collisions appear and there are some where all pairs form a collision. Of course, this won't happen for the special case here, but this remains to be shown. | |
